Sally drew a circle with right triangle PRQ inscribed in it, as shown below: The figure shows a circle with points P, Q, and R on it forming an inscribed triangle. Side PQ is a chord through the center, and angle R is a right angle. Arc QR measures 40 degrees. If the measure of arc QR is 40°, what is the measure of angle PQR? 20° 40° 50° 70°
